MORGAN W. BROWN, OF VEST FARMS, NEW YORK.

lMPROVED METHOD OF PREPARING PAPER FOR WRAPPING TOBACCO,'SNUFF. SOAP. AND OTHER Y ARTICLES.

Specification t'trmirg part ofLetters Patent No. 74, 195, dated February 11, 1868; antedated January 2 1868.

To all whom it may concern Be it known that I, ll/IORGAN W. BROWN, of West Farms, in the county of Westchester, in the State of New York, have invented a new and improved mode for the treatment and preparation of paper, cloth, and vegetable fibrous substances for the purposes and appllcation of inclosing, and protecting from drying, tobacco, snuff, soaps, drug's, chemical substances, paints, putty, also groceries, medicinal preparations, &c.; and I do hereby declare that theffollowing is a full and exactdescription thereof.

The nature of my invention consists in the use of a composition of glycerine and an alkali, glycerinc being the principal vehicle, and a caustic or carbonated alkali, auxiliary to the perfecting of this composition. of matter for the purposes of saturating or coating the paper or cloth, &c., preparatory to its application, to protect from drying various solid and powdered substances. H

To enable others skilled in the art to make, prepare, and use my material, and its appli- 'cation to the substances herein named, I will proceed"'to describe the mode and process,

aveak solution to about every one hundred parts ,of the glycerine, and. agitate the mixture;well'together until well mixed. The best method of mixing the two substances together is at the common temperatures; but it can also be heated, if necessary. This preparation I now use to saturate the paper, cloth, or vegetable fibrous-substances by applying it to the surfaces of the articles to be saturated with a brush orin any other convenient manv ner. I use a bath and the submersion of the paper, cloth, &c.; then drain it slightly, press it, and fold or,pack up. For use for boxes and other pasteboard packages they are saturated and the pores well filled, then simply drained. For all thick packages the solution can be moderately heated, as it will penetrate and saturate'the substance more rapidly. I

also find that the glycerine vehicle, in admire ture with alkaline solutions prepared and rendered weak and made from any of the solid caustic, carbonated, or silicated alkalies, answers the purpose; but I prefer the solutions made from the soda and potash alkalies. I also find that the common unbleached commercial glycerine is useful and more economica-l for the solutions, and I use it, as well as the, purified glycerine, depending altogether on the quality'ot' the substances to be incased and protected-as, for example, all drugs or medicines or substances used for food, as gro- "ceries, dry or semi-fluid. I use in substance the purified white glycerme to saturate the paper or other vegetable fibrous or wood materials used as coverings for the substances named hereinbefore; and I use and apply the common glycerine in admixture with a small percentage of the weak alkalies for the paper or cloth coverings for the wrapping and i11 articles to be protectedand the substances to be preserved. 15 to 20 is sufficient in most uses, and it can be used to advantage as dense as 30 or upward. The solution of soda, pearl-ash, or other carbonate, caustic, or silicated alkalies, I use generally at 2 to 5, and

sometimes above 5, Baum. A thin solution of soap may also at times be used 1n substitution for the alkaline solutions and adnnxted with the glycerine. I use any of the perfumes to impart fragrant odors tothe yel ig l e or solutions preparatory to the coating or immersion of the paper,.cloth, or vegetable fibrous substance with good efi'ect in many of its applications. 'Ialso use, where it is necessary to impart to the white ground of paper or cloth any of the well-known dyes, stains or colors for the purpose of ornamenting orbeautitying the same, the coloring matter being put into the solutions used for the purposes herei-nbefore named; and I can use any of the colored papers, cloth, 820., the same, and for the applications and uses herein specified in the same manner and for the same purposes.

I find by long practical experiments and tests which I have made on paper, cloth, &c.,

as Well as in its applications and utility and' value, as well as' economy, for the especial uses herein specified.

In mostuses I find that the common glycerine answers all the purposes, and is very cheap when purchased by the quantity, in

barrels; and I find-"that the packages, envel y to secure by Letters Patent, is-

op'es, and boxes saturated with this vehicle may also in some cases have an application of any of the oilor resinous varnishes or water and air proof coatings applied to the outside or exterior of the wrapper, package, or

a box as an additional protection to the process I have herein described and set forth; 'or I foils over and on the exterior of the prepared paper,-cloth, or vegetable fibrous substance, & c., as herein set forth.

I use this aforesaid preparation to all boxes and vessels of any form or size that has the properties of absorption, and composed and constructed of vegetable fibrous materials 'as wood, paper, &c.; also on sheets of paper, cloth, or vegetable fibrous substances before or after the same are formed into the shapeof envelopes, packages, boxes,- &c; or the use and. application of the solution over and on paper boxes, packages of cloth, wood, and paper that have been previously'and are coated with paints, colors, or any earthyporous cements, paints, colors, or washes containing oil or water colors.

What I claim as my invention, and desire A composition of matter as herein substantially set forth and-specified, and its'uses and application to the preparation andtreatment oipa-per, cloth, and vegetable fibrous substances, for the uses and purposes herein specified and set forth. can use any one of the tin or other metallic MORGAN W. BROWN.-
